{ 1 VALVE.

Application filed' October 19, 1927.

' By way of explanation, it might be stated that it is a known fact thatirrigating systems in common use are faulty because of the absence ofmeans to insure a uniform distribut-ion of the water.

The well known canal irrigating system, owing to the difierence in thecontour of the ground results in greater water pressure at certainpoints than at others, and while the overhead irrigation system hasproven the most eflicient, it has been found that various degrees ofwater pressure exist at different points on the pipe line, owing to thefact that the pipes run through high and low land, to the end that it isimpossible to insure a uniform pressure resulting in irregularprecipitation. 7

It is therefore the object of the present invention to provide a novelform of valve esspecially designed for use in irrigating systems whereinpipe lines are used, the primary object of the invention being toprovide means for regulating the flow of water to the precipitators oran irrigating system, insuring uniform precipitation at all times.

Another important object of the invention is to provide a valve of thistype which may be readily and easily secured to the riser pipe or pipesof an irrigating system, which pipes conduct the water to theprecipitators for distribution.

A still further object of the invention is to so construct the valvethat the water pressure will be equal both downward and upward and thepressure will be determined by the amount of water permitted to passinto the valve.

Another object of the invention is the provision of a valve which willpermit of a water pressure gauge being inserted therein so that a personmay determine with a degree of accuracy, the water pressure at aparticular point.

WVith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawing:

Figure 1 is an elevational view showing Serial No. 227,288.

a valve constructed in accordance with the present invention aspositioned on a riser pipe and supporting a precipitator.

Figure 2 is an enlarged vertical sectional view through thevalve.

Referring to the drawing in detail, the reference character 5 designatesthe main pipe line of an irrigating system of the overhead type, towhich the riser pipe 6 is connected and communicates with the interiorof the pipe, it being understood that these riser pipes are arrangedalong the main pipe of an irrigating system, predetermined distancesapart.

The valve includes a body portion 7 formed with a lateral downwardlyextended portion 8, communicating with the body portion through theopening 9 which is disposed intermediate the ends of the body portion sothat when water enters the body portion, the pressure of the wateragainst the plug 16 will cause the pipe to be held in position at alltimes.

The latera ly extended portion 8 is internally threaded to receive thethreaded end of the riser pipe to which the device is secured so thatwater from the main pipe line may be directed into the body portionthrough the riser pipe 6.

Supported within the body portion is the valve 10 which is in the formof a barrel, the same being provided with grooves to receive the packingrings 11 which insure a fluid-tight connection between the valve properand body to which the valve is positioned or supported.

Formed integral with the barrel 10 is an enlargement- 12 that definesashoulder at its lower end providing a rest for the barrel 10, it beingunderstood that the barrel 1O supports the weight of the precipitatorpipe 13 which is connected therewith through the union 14,

An opening indicated at 15 is formed in the barrel l0 and is designed tomove to a position opposite the opening 9 to regulate the passage ofwater through the valve proper, it being understood that the waterpressure passing through the valve may be regulated by movin the valveto cause a greater or less area of the opening to be brought before theopening 9.

The lower end of the barrel 10 is normally closed by means of the plug16 which plug however, may be removed so that a suitable water gauge maybe inserted in the barrel 10 to determine the water pressure passingthrough the valve. It will thus be seen that r with a water gaugepositioned in the barrel 10, the barrel 10 may be rotated until apredetermined pressure is registered on the gauge, whereupon the gaugemay beremoved and the plug 16 positioned to close the end of the barrel.7 v

It may be necessary to make adjustments of the valves throughout thelength of the main pipe line becauseof irregularities in thegroundsurface, which as before stated, cause uneven pressuresat theprecipitators.

After the adjustments along the main line of an irrigating system havebeen made, the

valves will be marked, to the end that it will not be necessary to makefurther adjustments or tests of; the water pressure to lnsure evenprecipitation.

The reference character 17 indicates a preeipitator which may be of anydesired construction. r V

I claim: V

A valve for irrigating systems including a vertical body portion, alateral downwardly extended portion adapted to be secured to a riserpipe of an irrigating system, a barrel having a shoulder at its upperend resting 011 the upper end of the body portion the lower end of thebarrel lying flush with the lower end of the body portion, a removableplug in the lower end of the barrel to close the lower end of thebarrel, said barrel having an opening adapted to register with thedownwardly extended portion to control the passage of water throughthebarrel. 7

In testimony that I claim the foregoing as my own, I have hereto affixedmy si nature.
